We consider analytically coupled circle maps (uniformly expanding and analy
tic) on the Z(d)-lattice with exponentially decaying interaction. We introd
uce Banach spaces for the infinite-dimensional system that include measures
whose finite-dimensional marginals have analytic, exponentially bounded de
nsities. Using residue calculus and 'cluster expansion'-like techniques we
define transfer operators on these Banach spaces. We get a unique (in the c
onsidered Banach spaces) probability measure that exhibits exponential deca
y of correlations.
